adjust it to fit our needs better:
* Call sensors_feature_get_type() before allocating memory for the
feature name. The allocation will be reverted for all sysfs files
which are not valid libsensors attributes, and there can be a lot
of these. So this saves a few memory allocations. But this means
that we want to pass a simple string to sensors_feature_get_type()
rather than a struct sensors_feature_data. This also means that
sensors_feature_get_type() gets the raw attribute name ("_input"
not stripped.)
* Get the channel number from sensors_feature_get_type() too. We
get it for free from sscanf(), so it's more efficient to return it
than to parse it again in sensors_read_dynamic_chip().

first called during the library initialization to generate the feature
tables. Then it is called again by sensors itself. This is because we
do not store the result the first time. I propose that we add a type
field to struct sensors_feature_data, where libsensors would store
the result of sensors_feature_get_type(). That way, the application
can get the information without calling sensors_feature_get_type()
again.
This change has the following benefits:
* Obviously, a small speed-up.
* sensors_feature_get_type() can be removed from the public interface.
This means that we can turn it into something that fits the
libsensors needs better, allowing for more optimizations (see next
patches.)
Note: the patch looks bigger that it really is, because I had to move
definitions around in sensors.h.

and sensors_chip_features_list arrays tend to track the same information.
So it's much more simple, and more efficient, to have a single array. I
decided to keep sensors_proc_chips, because it already has memory management
helpers. One nice side effect is that the arbitrary limit to the number of
supported chips is now gone. Another one is that some of the memory leaks
were fixed.

sensors_chip_features_list[]. Using only the prefix (as was done before)
makes it impossible to properly support multiple chips with the same prefix
but a different feature set.

identify sysfs entries. Reasons for this rewrite / bugs fixed:
-Don't give features like alarms / sensor type / fault flag a
compute mapping only a normal mapping
-Don't generate features for sysfs entries like uvent, modalias, etc.
instead only generate features for features known by
sensors_feature_get_type()
-Sort the list of found features logically instead of sorted in alphabet order
of the sysfs entry. So now it starts with all in entries, then all fan and
then all temp. Just like the order of most entries in lib/chips.c. Also
this means that it now contains in0 - in10 in that order and not in0, in10,
in1 - in9

abituguru seems to work well with the new dynamic chip support and generic
chip printroutines. note: the abituguru code should be completly removed in
the future.
-comment k8temp entry in lib/chips.c and prog/sensors/main.c, as the
k8temp seems to work well with the new dynamic chip support and generic
chip printroutines. note: the k8temp code should be completly removed in
the future.
-make the match for the subtype exact instead of a strncmp, otherwise
an alarm_enable flag gets classified as an alarm, leading to all sensors who
have their alarm enabled getting an alarm reported, as the alarm_enabled gets
read as alarm.
-and do the same for the _input match to check if this is a main or subfeature

compatibility only. This change is needed to match ongoing cleanups in
Linux 2.6's i2c-core. i2c adapters will soon be class devices only, the
legacy i2c_adapter devices and driver are being removed.

I2C algorithms no longer have names in Linux 2.6, and anyway they are
implementation details user-space doesn't care about. No third party
application is known to have ever used this particular feature of
libsensors. "sensord" and "sensors" no longer do.

prog/sensors: Clearer error messages when no sensors are found. The
most frequent cause is a lack of drivers, not procfs/sysfs problems.

This patch replaces the I2C chip enumeration (through sysfs) in lib/proc.c
with new functions in lib/sysfs (using libsysfs). The patch also updates
the init code accordingly.

This patch replaces the I2C bus enumeration (through sysfs) in lib/proc.c
with a new function in lib/sysfs (using libsysfs). The patch also updates

This patch adds the files lib/sysfs.h and lib/sysfs.c, beginning with a rewrite
of the sysfs detection code (using libsyfs). In the process, I replaced two
poorly named globals with better names, and moved them to sysfs.c. The sysfs
detection now happens very early during library init, rather than later.
The long term plan is for the two global variables to disappear anyway, as
everything to do with sysfs should get moved into lib/sysfs.c.
